Y = kinematic viscosity at 100 °C of the oil whose viscosity index is to be calculated, mm2/s, and H = kinematic viscosity at 40 °C of an oil of 100 viscosity index having the same kinematic viscosity at 100 °C as the oil whose viscosity index is to be calculated, mm2/s. 5.2.3 If U > H, calculate the viscosity index, VI, of the oil as follows:

Melt Flow Index is an assessment of average molecular mass and is an inverse measure of the melt viscosity; in other words, the higher a MFI, the more polymer flows under test conditions. Knowing the MFI of a polymer is vital to anticipating and controlling its processing. Generally, higher MFI polymers are used in injection
Calorific Value/BTU and Wobbe Index. The HFVM Viscomaster is a high performance, multivariable viscosity meter designed for the measurement and control of heavy fuel oil (HFO) that supply engines, turbines and burners in Marine and Power applications.

This is an apparent viscosity. In practice the word ‘apparent’ is often omitted and the symbol η is used. As flow testing is performed over a range of conditions (temperatures and/or piston speeds), the varia-tion of viscosity with temperature and rate of flow can be easily obtained by simple calculations. With
Viscosity 5 Viscosity coefficients Viscosity coefficients can be defined in two ways: • Dynamic viscosity, also absolute viscosity, the more usual one (typical units Pa·s, Poise, P); • Kinematic viscosity is the dynamic viscosity divided by the density (typical units m2/s, Stokes, St). Viscosity is a tensorial quantity that can be decomposed in different ways into two …
